The Sig Sauer P938 is one of the most popular micro-compact 9mm pistols on the market, and its slim aluminum frame makes it well-suited to IWB and pocket carry. The external thumb safety is a defining feature that sets the P938 apart from similar-sized competitors, and holster fit must account for it. These five picks are built to the P938’s specific dimensions and cover the range from appendix IWB to dedicated pocket carry.

Vedder LightTuck P938 — Best IWB Overall
Vedder molds the LightTuck shell specifically to the P938, giving full trigger guard coverage with no interference at the thumb safety. The retention screw adjusts the draw force precisely, and the single polymer clip keeps the slim profile needed for the P938’s micro frame. Ride height is adjustable, and the open bottom works with the stock and flush-fit magazines equally well.

Tulster Profile P938 — Best for Appendix Carry
The Profile’s short muzzle cut suits the P938’s compact dimensions, keeping the holster from riding down into the lap when seated. The claw attachment presses the grip inward against the body for minimal printing. This is a consistent top pick for carriers who use the P938 as their primary carry gun and want the speed advantage of the appendix position with a sub-3-inch barrel.

DeSantis Nemesis — Best Pocket Holster
The Nemesis is a pocket holster staple for compact and micro-compact pistols. Its sticky outer material grips the pocket lining and stays behind when you draw, while a smooth inner surface allows a clean pull. The trigger is fully covered, and the rectangular shape breaks up the gun’s outline in the pocket. This is the most affordable option on the list and works reliably for front-pocket carry in larger pockets.

Crossbreed MiniTuck — Best Hybrid for the P938
The MiniTuck is Crossbreed’s micro-compact-focused hybrid design, pairing a leather backer with a precisely formed P938 Kydex shell. It is notably smaller than the full-size SuperTuck, keeping the footprint proportional to the P938’s frame. A single steel clip holds the holster firmly while the leather conforms to the body over time. Good choice for carriers who find pure Kydex uncomfortable during extended wear.

Alien Gear ShapeShift IWB — Most Adjustable
The ShapeShift system allows cant adjustments from negative 15 to positive 15 degrees and multiple ride height settings, all without tools. For P938 carriers who are still dialing in their ideal carry position, the flexibility to make those adjustments without buying a new holster is genuinely useful. Retention is set via a dial on the shell.

How to Choose a Holster for the Sig P938
The P938’s thumb safety requires a holster profiled to that specific model — do not use a generic sub-compact holster. Decide between IWB and pocket carry based on your daily wardrobe and activity level. If you carry in a pocket, use a dedicated pocket holster every time. For IWB carry, check whether you need a claw attachment for reduced printing. Finally, verify the holster fits both the standard grip and the extended magazine without interference.

Frequently asked questions
Do I need a holster that clears the thumb safety on the P938?+
Yes. The Sig P938 has an external thumb safety, and a holster that covers or binds against it can interfere with your draw. Look for holsters specifically fitted to the P938 model rather than generic sub-compact fit, as the correctly profiled shell will leave the thumb safety fully accessible and unobstructed at all times.
Is the Sig P938 suitable for pocket carry?+
Yes, the P938's micro frame makes it one of the more pocket-friendly 9mm pistols available. A dedicated pocket holster breaks up the outline of the firearm, protects the trigger, and prevents the pistol from rotating in the pocket. Never pocket-carry without a holster designed for that purpose.
